    Summary
    Enables chromatin binding activity. Involved in several processes, including DNA endoreduplication; heterochromatin formation; and regulation of DNA-templated DNA replication. Located in chromosome. Is expressed in several structures, including dorsal pharyngeal muscle cell; embryonic hindgut; gastric caecum; larval muscle system; and pole plasm.
